New submitter kyrsjo (2420192) writes "The Economist has an article on how information technology — the real stuff, not just button-pushing — is making its way back to schools across the world. As the article argues: 'Digital technology is now so ubiquitous that many think a rounded education requires a grounding in this subject just as much as in biology, chemistry or physics.' In today's society, teaching computer science in schools is absolutely necessary, and that means getting a real understanding of computers and how they work. That requires working with algorithms and programming, not just learning which buttons to push in the program that the school happened to use."

Daniel_Stuckey (2647775) writes "If you were anywhere near the internet last week, you would have come across reports of 'DarkMarket', a new system being touted as a Silk Road the FBI could never seize. Although running in a similar fashion on the face of things — some users buy drugs, other sell them — DarkMarket works in a fundamentally different way to Silk Road or any other online marketplace. Instead of being hosted off a server like a normal website, it runs in a decentralized manner: Users download a piece of software onto their device, which allows them to access the DarkMarket site. The really clever part is how the system incorporates data with the blockchain, the part of Bitcoin that everybody can see. Rather than just carrying the currency from buyer to seller, data such as user names are added to the blockchain by including it in very small transactions, meaning that its impossible to impersonate someone else because their pseudonymous identity is preserved in the ledger. Andy Greenberg has a good explanation of how it works over at Wired. The prototype includes nearly everything needed for a working marketplace: private communications between buyers and sellers, Bitcoin transfers to make purchases, and an escrow system that protects the cash until it is confirmed that the buyer has received their product. Theoretically, being a decentralized and thus autonomous network, it would still run without any assistance from site administrators, and would certainly make seizing a central server, as was the case with the original Silk Road, impossible."

Hallie Siegel (2973169) writes in with news of a robotic competition with some serious goals. "Dr. Alaa Khamis writes: 'Detection and removal of antipersonnel landmines is, at present, a serious problem of political, economical, environmental and humanitarian dimensions in many countries across the world. It is estimated that there are 110 million landmines in the ground right now; one for every 52 inhabitants on the planet. These mines kill or maim more than 5,000 people annually. If demining efforts remain about the same as they are now, and no new mines are laid, it will still take 1100 years to get rid of all the world's active land mines because current conventional methods of removal are very slow, inefficient, dangerous and costly. Robotic systems can provide efficient, reliable, adaptive and cost effective solutions for the problem of landmines and unexploded ordnance (UXO) contamination. Minesweepers: Towards a Landmine-free World was initiated in 2012 as the first international outdoor robotic competition on humanitarian demining by the IEEE Robotics and Automation Society – Egypt Chapter, which won the Chapter of the Year Award in IEEE Region 8 that year. It aims to raise public awareness of the seriousness of landmines and UXO contamination and the role of science and technology in addressing these; it also aims to foster robotics research in the area of humanitarian demining by motivating professors, engineers and students to work on innovative solutions for this serious problem."

Hugh Pickens DOT Com (2995471) writes "Red Orbit reports that after nearly 50 years of warping across galaxies and saving the universe from a variety of alien threats and celestial disasters, Star Trek's William Shatner was honored with NASA's Distinguished Public Service medal, the highest award bestowed by the agency to non-government personnel. 'William Shatner has been so generous with his time and energy in encouraging students to study science and math, and for inspiring generations of explorers, including many of the astronauts and engineers who are a part of NASA today,' said David Weaver, NASA's associate administrator for the Office of Communications at NASA Headquarters in Washington. 'He's most deserving of this prestigious award.' Past recipients of the NASA Distinguished Public Service Medal include astrophysicist Neil deGrasse Tyson, former NASA Jet Propulsion Laboratory director and Voyager project scientist Edward Stone, theoretical physicist and astronomer Lyman Spitzer, and science fiction writer Robert Heinlein. The award is presented to those who 'have personally made a contribution representing substantial progress to the NASA mission. The contribution must be so extraordinary that other forms of recognition would be inadequate.'"

sciencehabit (1205606) writes "Scientists have found that mice feel 36% less pain when a male researcher is in the room, versus a female researcher. The rodents are also less stressed out. The effect appears to be due to scent molecules that male mammals (including humans, dogs, and cats) have been emitting for eons. The finding could help explain why some labs have trouble replicating the results of others, and it could cause a reevaluation of decades of animal experiments: everything from the effectiveness of experimental drugs to the ability of monkeys to do math. Male odor could even influence human clinical trials."

walterbyrd (182728) writes in with news about the end of the line for a Novell anti-trust claim against Microsoft. "The U.S. Supreme Court on Monday brought an end to Novell Inc's antitrust claims against Microsoft Corp that date back 20 years to the development of Windows 95 software. By declining to hear Novell's appeal, the court left intact a 10th U.S. Circuit Court of Appeals ruling from September 2013 in favor of Microsoft. The court of appeals unanimously affirmed the dismissal of Novell Inc's claims that Microsoft violated the Sherman Antitrust Act when it decided not to share its intellectual property while developing its Windows 95 operating system. Novell was seeking more than $3 billion."

concertina226 (2447056) writes "The real reason behind the downfall of the Roman Empire might not have been lead contaminating in the water, which is the most popular theory, but the use of concrete as a building material. Dr Penelope Davies, a historian with the University of Texas believes that the rise of concrete as a building material may have weakened ancient Rome's entire political system as Pompey and Julius Caesar began 'thinking like kings'. Concrete was used to build many of Rome's finest monuments, such as the Pantheon, the Colosseum and the Tabularium, which have lasted the test of time and are still standing today."

Hugh Pickens DOT Com (2995471) writes "The NYT writes in an editorial that for the last few months, the Koch brothers and their conservative allies in state government have been spending heavily to fight incentives for renewable energy, by pushing legislatures to impose a surtax on this increasingly popular practice, hoping to make installing solar panels on houses less attractive. 'The coal producers' motivation is clear: They see solar and wind energy as a long-term threat to their businesses. That might seem distant at the moment, when nearly 40 percent of the nation's electricity is still generated by coal, and when less than 1 percent of power customers have solar arrays. But given new regulations on power-plant emissions of mercury and other pollutants, and the urgent need to reduce global warming emissions, the future clearly lies with renewable energy.' For example, the Arizona Public Service Company, the state's largest utility, funneled large sums through a Koch operative to a nonprofit group that ran an ad claiming net metering would hurt older people on fixed incomes (video) by raising electric rates. The ad tried to link the requirement to President Obama. Another Koch ad likens the renewable-energy requirement to health care reform, the ultimate insult in that world. 'Like Obamacare, it's another government mandate we can't afford,' the narrator says. 'That line might appeal to Tea Partiers, but it's deliberately misleading,' concludes the editorial. 'This campaign is really about the profits of Koch Carbon and the utilities, which to its organizers is much more important than clean air and the consequences of climate change.'"

An anonymous reader writes in with this bit of news about the Mars rover Curiosity. "NASA's Curiosity Mars rover is using several tools this weekend to take a closer look at a sandstone slab being assessed as a possible drilling target. If it fits the bill, the target could become Curiosity's third drilled rock. 'Windjana,' named after a gorge in Western Australia, would be the mission's first drilled rock that is not mudstone. To determine whether Curiosity should drill at Windjana, engineers have asked the rover to perform a number of tasks, including observations with the camera and X-ray spectrometer located at the end of the its arm and interpretations of composition at different points on the rock with a device that fires laser shots from the rover's mast."

The new breed of Aedes aegypti has been given a lethal gene. The deadly flaw is kept in check in the lab, but the mosquitoes soon die in the wild.'"

StartsWithABang (3485481) writes "Just a second after the Big Bang, the Universe was a hot bath of radiation, with a small fraction of protons and neutrons in about equal numbers left over. By time it was four minutes old, it was 92% hydrogen (by number of atoms) and 8% helium. Yet the Universe has aged nearly 14 billion years since then, and have formed many generations of stars, all of which burn hydrogen into heavier elements. So how much hydrogen is left, and how much will be left far into the future? A lot more than you might think."
